The long-term follow-up study will be blinded until the primary study is unblinded and will be open for all visits subsequent to unblinding of primary study HPV-013 (NCT00196924). During the open phase, only subjects who received the HPV-16/18 VLP/AS04 vaccine during the primary study will continue their participation in the follow-up study until Month 48. Subjects in the Control group (Havrix®) will attend one further visit as their last study visit.
